First Half Notes: Offensive coordinator Mike Martz very much wanted to stick it to his former team, just check out the number of times he used a 7-step drop. The Lions knew it; on 49ers pass plays they only had a safety deep four times and on one of them they were burned for a 24-yard touchdown pass to tight end Delanie Walker. … Isaac Bruce reminds me of Jerry Rice in his route running. He never gives anything away. On his 6-yard touchdown pass, he had cornerback Leigh Bodden so convinced he was running a post that when Bruce broke back to the corner, Bodden slipped leaving Bruce wide open for the score. … All of O’Sullivan’s incompletions were passes to Vernon Davis and I put Davis down for two drops on tough chances. The first was a ball thrown a little behind him on a roll out play; the second was a long pass that Davis got his fingers on. Commentator Brian Billick said Davis looked back for the ball too early. … A few times previously in the red zone this year, the 49ers were called for an illegal formation. O’Sullivan’s getting better at recognizing when things are off. In the first quarter, he noticed Bryant Johnson was the eighth man up on the line of scrimmage and O’Sullivan backed him off to avoid a penalty. Another improvement was the 49ers in the red zone where they threw more accurately and only had one mistake – the drop by Davis. It looked like Adam Snyder played in the first quarter and David Baas replaced him a left guard in the second half. … The Fox crew said that rookie Josh Morgan lost 15 pounds while battling a flu virus for the last month.
